Elixir + Ash is so good, and AI works very well with it because it can understand the domain you are working in. LiveView is amazing, not just for internal tools. I would even say that in most cases it will outperform flashy UIs, because it focuses on actual users who work with the app every day, not people who just want to be impressed for a minute
The truth is that I put a lot of work in at the beginning to define the data structure and flows by myself. AI was very useful later to experiment with how to build the views on top of it and to fix some issues.
I still had to think hard about how to make this simple and easy for someone who does not have deep knowledge of this manufacturing domain.
*Lessons learned:*
1. Data structure is almost everything, then comes business logic
2. You must have deep domain knowledge of what you are building
3. Iterate fast on the views built on top of the data structure
*PS*
All mobile fixed had been resolved and deployed ;)
